When two or more species live in proximity and share the same basic
requirements, they usually compete for resources, habitat or territory.
Only the strongest prevails, driving the weaker competitors to
extinction. This is the principle of competitive exclusion (also
known as Gause's law). One species wins because its members are more
efficient at finding resources, which leads to an increase
in population. This means that a population of competitors finds less
of the same resources and cannot grow at its maximal capacity [1]}.
